Abstract excerpt

The NarX-NarL and NarQ-NarP sensor-response regulator pairs control Escherichia coli gene expression in response to nitrate and nitrite. Previous analysis suggests that the Nar two-component systems form a cross-regulation network in vivo. Here we report on the kinetics of phosphoryl transfer between different sensor-regulator combinations in vitro. NarX exhibited a noticeable kinetic preference for NarL over...
